GAS-BURNER.

Specification of Letters Patent.

Patented. Dec. 3, 1 9%? Application filed February 8. 1907- Serial No.356.392.-

To all whom it may concern:

Be it known that I, GILBERT A. Cnor'ro, a citizen of the United States,residing at Reading, county of Berks, State of Pennsylvania, haveinvented a new and useful Gas- Burner, of which the following is aspecifica- My present invention consists of a novel and usefulconstruction of a gas burner by the employment of which the amount ofgas which it is necessary to use is reduced to a minimum and not only amore economical but a better light is produced;

It further consists of a novel COIlStI'llGtlOD of a container which isadapted to be readily inserted in burners now in use and comprises inits broad scope'a casingor sleeve, the upper and lower ends of which areapertured, said apertures being closed by means of ca s of gauze orother suitable material and t e space within the sleeve or containerbetween said caps is filled with mineral-wool, cotton,

asbestos, animal wool or any equivalent material, although I have foundin pra'ctice that a combination of mineral wool and animal wool givesreliable and satisfactory results.

It further consists of other novel features of construction, all as willbe hereinafter iully set forth.

For the purpose of illustrating my-inv'en tion, I have shown in theaccompanying drawings embodiments thereof which have been found inpractice to give'satisfactory andreliable results, although it is to beunderstood that the various mstrunientalities of which my inventionconsists may be variously arranged and organized and that my inventionis not limited to the precise arrangement and organization of theseinstrumentalities, as in the embodiments herein shown.

Figure 1 represents a side elevation of a gas bracket showing insectional elevation a gas burner embodying my invention attachedthereto. Fig. 2 represents a erspec tive view of the contaiueremploye indetached position. Fig. 3 represents a side elevation of a portion of abracket showing in sectional elevation another embodiment of myinvention. Fig. 4 represents a rspective view, showing a container for te min- Similar numerals'ei reference indicate cor. responding parts in'the figures.

eferring to the drawings, 1 designates the rod of a gas burner havingsecured thereto an elbow or extension 2, the upper end oi which isthreaded in the usual manner,

adapting the same to coact with the internal thread 3 of the burnercasing 4:. T he casing 4 at its lower end is provided with an enlargeddiameter 5' from which extends upwardly a smaller diameter 6, and thecasing 4 is still further reduced to form a shoulder 7 and a reduceddiameter 8.

9 designates a burner of the usual construction which is adapted to beretained in the reduced end 8 of the gas burner casing 425 10 designatesa sleeve, tube or container, preferably of brass or aluminium which isadaptedto closely engage the reduced diameter 0r bore 6 of the casing 4,said sleeve or tube having inserted in its upper end a strainer or gauze11, it being noted, as seen in Fig. 1, that a similar strainer or gauze12 is employed to clos'e the lower end of said container, the ends ofsaid strainers or caps Hand 12 being deflected inwardly so as to engagethe internal walls of the sleeve 10.

-The s ace between the caps 11 and 12 within the seeve I0 is filled withmineral wool, natural wool, cotton or equivalent material or acombination of such materials, it being apparent that any impropermovement of. said material after it is placed within the tube or sleeve10 is positively prevented owing to the manner in which the caps 11 and-12 are carriedwithin the tube or sleeve 10,

said caps being preferably flush with, or terminating slightly withinthe ends of the tube or sleeve 10. The end of the casin 10 is adapted toabut against the shou der 7 formed by the reduced diameter of the gasburner casing 4, as will be readily apparent from Fig. 1.. r

In the embodiment shown inFigs. 3 and 4,

I have shown a slightly modified construc.-

tion, although it Wlll be apparent that the same principle is employedand the same result attained by the employment of such a construction.In this embodiment, 13 designates a bracket having a threaded extension14 on which the lower portion or sleeve 15 of eral wool or equivalentmaterial, in detached the casing 16 is ada ted to be screwed orposition.

otherwise secured.

he lower casing 15 is deflected outwardly at its upper end, as seen at17, and 1s Internally threa ed so as to form a shoulder 18.

19 designates the upper casing member, the lower end of which isthreaded and adapted to engage with the internal thread of the deflectedportion 17 of the lower casing and thus secure the two casing members 19and 16 in fixed relation with each other. The casing 19 converges or isdeflected inwardly,

as seen at 20,'and from this converging portion 20 extends a reduceddiameter 21 within the end of which the tip 22 of the usual constructionis adapted to be seated.

23 designates a sleeve, tube, or container, the outer contour of whichis such that it is of t e portions 16 and 19 of the two casing membersand this sleeve or container is adapted to be filled with mineral wool24 in a similar manner to that already indicated with respect to Figs. 1and 2, it being noted that the upper end of this container 23 is.

closed by means of a screen or gauze cap 25 and that the lower end 1sclosed by means of ascreen or gauzecap 26. In the present instance,however, instead of employing a I The manner in which my novel gasburner is assembled will be readily a parent to those skilled in theart, and in the embodiment seen in Figs. 1 and 2, it is simply essentialto fill the sleeve 10 with mineral or'animal wool or other suitablematerial and then insert the gauze caps 11 and 12 in osition after whichthe sleeve 10 is inserte in the casing 4 so that it will closely engagethe internal diameter 6 and abut against the shoulder 7 of said casing4.

In the embodiment seen in Figs. 3 and 4, the container 23 is filled withmineral wool, animal wool or equivalent material after which the gauzecaps 25 and 26 are inserted in each end. Theends of the container 23 arethen swaged in any suitable manner so that the container 23 will conformto the internal diameter of the portions 16 and 19 of the two casingmembers when the parts are in assembled position. The sleeve 15 of thelower casing is secured in place on the extension 14 of the bracket 13.The container '23 is then placed within said lower casing so that thelower converged end thereof rests upon the upper end of the threadedsleeve or tube 14. 1 1e upper casing is then placed over the upper endof the container 225 and adapted to closely engage the inner diametermore perfect combustlon will be obtained.

owing to the employment of the threads at the end thereof and theinternal thread on the deflected. portion 17 of the lower casing, thetwo parts may be readily united so that there is .no possibility of anyimproper movementof the container 23 relative to the upper and lowercasing members of the burnpr, and the upper aperture 27 of the container23 will register with-the reduced diameter 21 of the upper casingmember.

The gas passing through the gas burner will be obliged to pass throughthe up er and lower screens or ape'rtured caps and t ough the mineralwool, animal wool, cotton or' equivalent material or a combination ofsuch material so that any foreign material will be removed therefrom.

There is often difficulty in gas burners of this type owing to the gashaving too large a proport on of air, so that a proper mixture of airand gas is not supplied to the burner tip. When a construction embodyingmy invention is employed the passage of the gas to the tip will beobstructed in such a manner that the air and gas will be brought intointimate contact with each other so that as the mixture passes from thechamber 8 or 21 to the burner tip 9 or 22 respectively, the gas and airwill form. a homogeneous product and a It is a well known fact that thepressure of the gas passing through the conduits in cities and townsvaries a great dealat difi'erent hours of the day, the ressure beinggreater during the day and v decreasing proportionally at night whenmore lights are employed. When a construction embodying my invention isemployed the variation in the pressure of the gas at the burner tip isreduced to a minimum, since the same must pass through the comminutedmaterial within the container before it "reaches said burner tip. Aconstruction embodying my invention can be readily employed in burnersnow in use and can be readily and quickly assembled or disassembled whendesired.

It has been found in practice that by the employment of a constructionsuch as herein illustrated and described, the-amount of gas used islargely decreased andthereby the cost of operating said lights andfurthermore a better and more efficient light is produced.

It will now be apparent that I have devised a novel and usefulconstruction of a gas, burner which embodies the features of advantageenumerated as desirable in the statement of invention and the abovedescription and while I have in the present instanceshown and describedembodiments thereof which have beenfound in practice to givesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit and sco e of the invention or sacrificing any of its avantages. l30
